ATTACHMENT FOR MUSIC-STANDS.

Specification of Letters Patent.

Application filed May 28, 1910. Serial No. 563,971.

To all 'whom "it may concern:

j Be it known that I, ARCHIBALD B. GRUBER, a citizen of the UnitedStates, residing at Portland, in the county of Multnomah and State ofOregon, have invented a new and useful Attachment for Music Stands, ofwhich the following is a specification.

This invention relates to attachments for music stands and moreparticularly to means whereby different instruments, such as clarinets,saxophones, iutes, etc., may be securely held while not in use and insuch a manner that they can be readily detached.

A further object is to provide an attachment of this character whichwill not mar the instrument placed therein.

A still further object is to provide a holder capable of supportingseveral instruments at a time.

With these and other objects in view the invention consists of certainnovel details of construction and combinations of parts hereinafter morefully described and pointed out in the claims.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings Figure 1 is a plan view of the attachment, the standardof the music stand being shown in section therein. Fig. 2 is a sectionon line A-B Fig. 1. Fig. 3 is a section on line C-D Fig. 1. Fig. 4 is asection on line E-F Fig. 2.

Referring to the figures by characters of reference 1 designates a blockconstituting the body of the attachment, this block being provided withan arcuate jaw 2 extending from one face and the concave surface ofwhich merges into the wall of a recess 3 formed in said face of theblock 1. A detachable and adjustable arcuate jaw 4 is adapted tocoperate with the jaw 2 and extends from a plate 5 adapted to contactwith one faceof the block 1 and to abut against a stop rib 6 formed onsaid face. A tubular extension 7 projects from one face of the plate 5and into a bore 8 formed in the block 1, this sleeve being interiorlyscrew threaded as indicated at 9 so as to be engaged by a screw 10 whichis centrally located withinl the bore 8 and is swiveled in the inner endwall of the bore, as shown at 11. A head 12 is secured to and rotateswith the screw 10 and by means thereof said screw can be actuated so asto shift the extension 7 longitudinally within the bore 8 and thus movethe plate 5 toward or away from the block 1.

Oppositely extending arms 18 and 14 are formed on or secured to theblock 1 and each of these arms isl provided at its outer end with anarcuate jaw 15, there being ears 16 upon the arm and close to the jaw. Alever 17 is fulcrumed between the ears 16 and has an arcuate jaw 18 uponone end and which is similar to the jaw 15. A spring 19 is interposedbetween each lever 17 and the adjoining arm and serves to hold a jaw 18with its ends normally contacting with the ends of the jaw 15. Each ofthe jaws 15 and 18 is preferably semi-circular so that, when the twojaws contact, a circle is outlined thereby. Ears 20 extend from each arm13 and 14 and have arms 21 pivotally mounted between them, there beingclamping screws 22 extending through the ears 20 and arms 21 for thepurpose of binding the ears upon the arms and thus locking said armsagainst movement relative to the arms 13 and 14. Each arm 21 has anarcuate jaw 23 at its Outer end and ears 24 disposed adjacent the jaw,these ears having a lever 25 fulcrumed between them and carrying anarcuate jaw 26. A spring 27 is interposed between each arm 21 and lever25 so as to hold the jaw 26 normally pressed against the jaw 23. Thesejaws 28 and 26 are similar to the jaws 15 and 18 and each of them has alining 27 of felt or the like the ends of which are looped or foldedupon the ends of the jaws and secured thereto by means of small screws28 or the like. Intermediate portions of the linings may be attached tothe jaws by means of an adhesive or, if preferred, small screws similarto those shown at 28 may be employed for this purpose. The jaws 2 and 4are also provided with linings of felt or the like which may be attachedto them in the same manner.

In using the device the screw 10 is rotated so as to shift extension 7longitudinally and thus move the plate 5 and the jaw 4 away from theblock 1. The standard 29 of the music stand is then inserted between thejaws 2 and 4 and by rotating the screw 10 in the opposite direction, theextension 7 can be drawn into the bore 8 and jaw 4 thus caused to clampthe standard against the jaw 2. Rib 6 of course prevents the plate 5 andjaw l from swinging out of position after the parts have been properlyadjusted to the standard. Vhenever it is desired to place an instrumentwithin the holder, the lever 17 or 25 of the selected part is pressedback against the stress of its spring so as to swing the jaw of saidlever away from the opposed jaw l5 or 23. The instrument is theninserted between the two jaws and the lever released. The spring willpromptly shift the lever and its jaw back to their normal positions andthe instrument will therefore be tightly clamped between the two jaws.

Although four sets of instrument engaging jaws have been shown upon theattachment illustrated in the drawings, it is to be understood that thisnumber may be increased or diminished as desired.

Various changes may be made in the construction and arrangement of theparts without departing :trom the spirit or sacriicing any of theadvantages of the invention as dened in the appended claims.

What is claimed is l. An attachment for music stands includingadjustably connected standard engaging jaws, an arm supported thereby,an instrument engaging aw ixed relative to the arm, and a springcontrolled instrument engaging jaw movably mounted on said arm.

2. An attachment for music stands including a body portion, a jaw lixedrelative thereto, a jaw adjustably and detachably mounted upon the body,the two jaws cooperating to engage the standard otl a music stand, anarm supported by the body, an instrument engaging aw upon the arm, and aspring pressed instrument engaging jawY movably carried by said arm.

3. An attachment ot the class described including a body, a standardengaging jaw fixed relative thereto, a movable standard engaging jaw,means within the body for locking said jaw against movement, an armsupported by the body, relatively fixed and movable instrument engagingaws upon the arm, a spring for holding the movable jaw normally in a-predetermined position, and an actuating lever extending from themovable jaw.

4t. An attachment of the class described including a body, a fixed awextending therefrom, a plate movably mounted on one tace of the body, ajaw extending therefrom, means on the body for holding the plate againstrotation, coperating means upon the plate and body for binding saidplate upon the body, an arm supported by said body, relatively ixed andmovable instrument engaging jaws upon the arm, a spring for holding themovable jaw normally in a predetermined position, and an actuating leverconnected to the movable jaw.

5. An attachment of the class described including standard engagingjaws, an arm supported thereby, a second arm pivotally connected to thetirst mentioned arm, means for securing the pivoted arm against movementrelative to the other arm, a fixed jaw carried by each arm, a springpressed movable jaw carried by each arm, and an actuating leverextending from each of the movable jaws.

G. An attachment ot' the class described including standard engagingjaws, means for binding the jaws upon a supporting standard, an armseated relative to one ot the aws, a second arm pivotally supported bythe iirst mentioned arm, means for locking the pivoted arm againstmovementrelative to the other arm, relatively xed and movable awscarried by each arm, a spring for holding each movable jaw in apredetermined position, means for shifting the movable jaw, and a liningupon each jaw, the ends or' the lining being folded upon the ends ot thejaw.

ln testimony that I claim the foregoing as my own, I have hereto atiixedmy signature in the presence of two witnesses.

ARCHIBALD B. GRUBER.
